Sarah gets to class

Sarah's nipples were still poking through her wet, pink crop top when she got to her stop. She hurried to her class and tried not to make eye contact, but she still noticed her classmates checking her out. She saw Evan from Psychology and Marcie from Life Drawing, but she felt like everyone was looking at her barely clothed body. She blushed a deeper red and ducked into her Physical Geography classroom.

She sat in the back by Emma. Emma's hair was dyed black with purple highlights. She was wearing a black tanktop with black tights and a black pleated skirt. Her lipstick was black.

Sarah sat down and found her legs drawing inexorably apart. She had to do it. Her fingers brushed her thigh.

Emma glanced sideways and bit her black lips when saw what Sarah was doing and how little she was wearing.

"Do it, bimbo," the voice said in her ear.

Sarah pulled up her white miniskirt as dirty old Professor Higgins droned at the front. Her fingers pushed into the lips of her pussy and found her clit. Emma watched as Sarah toyed with herself more and more, and eventually a soft moan escaped.

Professor Higgins turned. He could see straight up Sarah's skirt, as the tiny amphiteatre table hid nothing.

"Class... what is subsidence?" he asked after a pause.

"I dunno," Sarah called out as she frigged herself in full view of the professor and Emma. "Is it, like, when you've had too many beers in one night?"

The class laughed.

"You should come by my office hours after class, Sarah," Professor Higgins replied.
